My favorite episode is without a doubt, Episode 216: I can't remember a damn thing about the factory tour. It really has that classic Gintama feel, with great comedic timing, a decent amount of the A-List crew showing up, including the lovable Madao-San. In a single episode, they develop a running joke, expand upon that joke, create an entire history for the joke, and build it up to a point where it can bring a man to tears. When I hear the word Patriot, this is the first thing that comes to mind and this episode never fails to get a chuckle out of me no matter how many times I watch it. "A job is supposed to be painful. That's why it's important to look for pain you enjoy." and other memorable quotes like that are one of the main reasons you watch Gintama, so you can learn to live your everyday life standing tall and doing your best. My only criticism is that Katsura was once again on standby.
